uninstalling a specific version of a python package in a specific directory

I want to uninstall the version 1.16.5 of numpy in a specific directory using pip in command prompt. This is what I have written:

C:\Users\DSP>pip uninstall --target=C:\ProgramData\Anaconda3 numpy==1.16.5

This is what appears:

Usage:
  pip uninstall [options] <package> ...
  pip uninstall [options] -r <requirements file> ...

no such option: --target

How can I solve this problem?
